A missing, cracked, or bridged Damp Proof Course lets ground moisture climb up brick and stone walls by capillary action, carrying dissolved salts with it. The visible symptoms follow a predictable script: paint bubbles and peels, plaster blisters and drums, skirting timber rots, and a tide-mark of efflorescence creeps up the wall regardless of how many coats of waterproof paint go on top. Because the moisture source is inside the capillary structure of the masonry itself, surface treatments rarely hold for long — the wall keeps wicking water from below.\n\nSamafit VK is MC-Bauchemie’s answer to exactly this problem, and it works from inside the wall rather than on its surface. It is a remedial, chemical alternative to physically cutting a new DPC course into an existing wall — a job that is disruptive, structurally risky on load-bearing or heritage masonry, and often impractical on monuments and old structures built with unconventional materials. Instead, a row of angled holes is drilled at the lowest practical point on the wall, and the two liquid components are introduced separately so they react and gel inside the capillaries themselves. Space Arc supplies and applies Samafit VK as part of MC-Bauchemie’s damp-proofing system for Delhi NCR clients, usually alongside MC-Fix-ST for plugging the drilled holes and, where surfaces are still wet at the time of treatment, Dichtament DS for surface-level waterproofing.”,”technicalInsight”:”The mechanism at work is often called silicification: the two Samafit VK components are formulated to stay unreactive on their own, but when introduced into the same capillary network in sequence, they combine and precipitate a gel that coats the internal pore walls. That gel does two things — it partially occludes the finest capillaries and, more importantly, it changes the wettability of the pore surface from hydrophilic (water-attracting) to hydrophobic (water-repelling). Capillary rise depends on water \”wetting\” the pore wall; once the wall is rendered non-wettable, the physics that pulls groundwater upward against gravity simply stops working. This is a different approach from cementitious crystalline waterproofing (which blocks pores mechanically) or surface DPC creams (which sit near the surface) — Samafit VK is designed to travel with the absorption front and react deep inside the masonry, which is why the drilling pattern, hole depth, and absorption time in the method statement matter as much as the material itself.”,”applications”:[“Retrofitting rising-damp control in older masonry residences, independent houses, and heritage bungalows across Delhi NCR”,”Ground-floor and plinth-level walls in buildings where the original DPC has failed, was bridged, or was never installed”,”Boundary and compound walls adjoining flowerbeds, lawns, or landscaped beds where soil stays in continuous contact with masonry”,”Structures in high-water-table pockets — riverside colonies, low-lying plots, and older South and East Delhi neighbourhoods”,”Splash-zone protection at the base of external walls repeatedly wetted by monsoon driving rain”,”Heritage and monument conservation work where cutting a physical DPC into the masonry is not an option”,”Godowns, warehouses, and industrial masonry walls showing salt efflorescence and peeling plaster from ground moisture”,”Pre-plastering and pre-painting remedial prep on damp-affected walls before a repaint or replaster cycle”],”advantages”:[“Non-invasive — no need to break open courses or cut a physical DPC into a load-bearing or heritage wall”,”Suited to brick, stone, and unconventional heritage masonry, not just modern block construction”,”Simple hand-tool application (masonry drill, spouted can, funnel or drip bottle) — no specialised injection pump needed for absorbent walls”,”Reacts in place to form a gel lining rather than a temporary surface coating, so the treatment stays where it’s needed”,”Cuts down the moss, fungus growth, timber decay, and salt efflorescence that come with chronic rising damp”,”12-month shelf life and a transparent-to-light-brown liquid that leaves no visible residue on the finished wall”,”Space Arc’s applicator team handles hole-spacing, dosing, and the VK1/VK2 sequencing on site rather than leaving it to guesswork”,”Slots into a complete MC-Bauchemie damp-proofing package with MC-Fix-ST for hole-plugging and Dichtament DS or Nisiwa SH where surface waterproofing is also needed”],”limitations”:[“A remedial treatment for existing rising dampness — it is not a substitute for installing a proper physical DPC during new construction”,”Performance depends heavily on wall porosity; very dense, glazed, or heavily painted masonry absorbs poorly and may need pressure injection or a different system altogether”,”Walls with hidden cavities, cracks, or voids connecting the drilled holes can drain the material away before the capillaries are saturated — the TDS explicitly calls for a water test before injection”,”Results aren’t instant: treated walls need roughly 2-3 weeks to dry out, and old damp plaster and paint must be stripped (they still hold salts) before replastering”,”Not a fix for hydrostatic or pressure-driven water ingress below grade — that calls for a membrane system such as Dichtament DS, not a capillary DPC injection”,”The manufacturer datasheet doesn’t publish independent lab figures for capillary water-absorption reduction, so performance is judged on site trial and applicator experience rather than a headline test number — worth a trial hole on unfamiliar substrates”],”bestPractice”:”Drill at the lowest practical point on the wall, close to where the original DPC line should sit, in a zigzag pattern — roughly 30 cm horizontal spacing and 15-20 cm vertical spacing, tightened up on denser, lower-absorption substrates.

Always run a water test first to rule out hidden cavities or cracks that would just drain the product away. Pour Samafit VK1 first and let it absorb until uptake slows and the level holds steady; follow up 30-60 minutes (never more than an hour) later with VK2, or VK3 for stubborn dampness, repeating the full cycle the next day if the wall keeps drinking it in.

The technical insight

The mechanism at work is often called silicification: the two Samafit VK components are formulated to stay unreactive on their own, but when introduced into the same capillary network in sequence, they combine and precipitate a gel that coats the internal pore walls. That gel does two things — it partially occludes the finest capillaries and, more importantly, it changes the wettability of the pore surface from hydrophilic (water-attracting) to hydrophobic (water-repelling). Capillary rise depends on water “wetting” the pore wall; once the wall is rendered non-wettable, the physics that pulls groundwater upward against gravity simply stops working. This is a different approach from cementitious crystalline waterproofing (which blocks pores mechanically) or surface DPC creams (which sit near the surface) — Samafit VK is designed to travel with the absorption front and react deep inside the masonry, which is why the drilling pattern, hole depth, and absorption time in the method statement matter as much as the material itself.

Where it is used

• Retrofitting rising-damp control in older masonry residences, independent houses, and heritage bungalows across Delhi NCR
• Ground-floor and plinth-level walls in buildings where the original DPC has failed, was bridged, or was never installed
• Boundary and compound walls adjoining flowerbeds, lawns, or landscaped beds where soil stays in continuous contact with masonry
• Structures in high-water-table pockets — riverside colonies, low-lying plots, and older South and East Delhi neighbourhoods
• Splash-zone protection at the base of external walls repeatedly wetted by monsoon driving rain
• Heritage and monument conservation work where cutting a physical DPC into the masonry is not an option
• Godowns, warehouses, and industrial masonry walls showing salt efflorescence and peeling plaster from ground moisture
• Pre-plastering and pre-painting remedial prep on damp-affected walls before a repaint or replaster cycle

Key advantages

• Non-invasive — no need to break open courses or cut a physical DPC into a load-bearing or heritage wall
• Suited to brick, stone, and unconventional heritage masonry, not just modern block construction
• Simple hand-tool application (masonry drill, spouted can, funnel or drip bottle) — no specialised injection pump needed for absorbent walls
• Reacts in place to form a gel lining rather than a temporary surface coating, so the treatment stays where it’s needed
• Cuts down the moss, fungus growth, timber decay, and salt efflorescence that come with chronic rising damp
• 12-month shelf life and a transparent-to-light-brown liquid that leaves no visible residue on the finished wall
• Space Arc’s applicator team handles hole-spacing, dosing, and the VK1/VK2 sequencing on site rather than leaving it to guesswork
• Slots into a complete MC-Bauchemie damp-proofing package with MC-Fix-ST for hole-plugging and Dichtament DS or Nisiwa SH where surface waterproofing is also needed

Limitations & considerations

• A remedial treatment for existing rising dampness — it is not a substitute for installing a proper physical DPC during new construction
• Performance depends heavily on wall porosity; very dense, glazed, or heavily painted masonry absorbs poorly and may need pressure injection or a different system altogether
• Walls with hidden cavities, cracks, or voids connecting the drilled holes can drain the material away before the capillaries are saturated — the TDS explicitly calls for a water test before injection
• Results aren’t instant: treated walls need roughly 2-3 weeks to dry out, and old damp plaster and paint must be stripped (they still hold salts) before replastering
• Not a fix for hydrostatic or pressure-driven water ingress below grade — that calls for a membrane system such as Dichtament DS, not a capillary DPC injection
• The manufacturer datasheet doesn’t publish independent lab figures for capillary water-absorption reduction, so performance is judged on site trial and applicator experience rather than a headline test number — worth a trial hole on unfamiliar substrates

How we position MC-Bauchemie Samafit VK

Samafit VK is the injection-based half of MC-Bauchemie’s rising-damp system in India; on site it’s almost always specified alongside MC-Fix-ST (for plugging the drilled holes) and, where the wall is still visibly wet, Dichtament DS for surface-level waterproofing or Nisiwa SH as an external water-repellent finish coat — Space Arc can package all three for a single damp-remediation job. Within the broader Indian construction-chemicals market, Fosroc’s mainstream catalogue doesn’t carry a direct, manufacturer-backed equivalent to a two-component gel-forming capillary DPC injection like Samafit VK; the nearest comparable approach tends to come from specialist silicone or siloxane-based DPC injection creams sold by regional damp-proofing contractors rather than a major multinational brand. For a project team that wants a documented system, applicator support, and a single point of accountability from drilling pattern through to replastering, Samafit VK backed by Space Arc’s MC-Bauchemie applicator team remains the straightforward choice.
