Rising damp is one of those problems that looks simple from the outside but causes real damage if left untreated. Sovereign DPC Injection Cream is a well-regarded solution that reinstates or creates a new damp proof course in existing masonry walls without the disruption of traditional chemical injection methods. The cream format makes it far easier to handle than low-viscosity fluids, stays where you put it, and diffuses into the wall over time to form an effective moisture barrier. If you have treated rising damp before with liquid injection systems, you will immediately appreciate the difference.
The product comes in a 600cc sausage cartridge, which fits standard skeleton or sausage guns. Application is clean, predictable, and significantly less messy than older injection approaches. Drill your holes at the correct centres, load the cartridge, inject the cream, and plug the holes. The cream migrates through the masonry capillaries over several weeks and cures to form a continuous hydrophobic barrier at the base of the wall.
Where Sovereign DPC Injection Cream Gets Used
This product is used across a wide range of masonry types including solid brick, stone, and block walls. It is particularly common in older properties where the original DPC has failed, bridged, or was never installed in the first place. Property renovators, damp proofing contractors, and builders tackling period properties reach for DPC injection cream regularly. It is the kind of product that earns its place on the van permanently once you have used it a few times.
The sausage format reduces waste compared to larger bulk containers, which matters when you are working across multiple smaller jobs. One 600cc cartridge treats a meaningful run of wall at standard injection centres, making it easy to price up jobs without overbuying. Not glamorous work, but done correctly it is effective and long-lasting.
Pro Tip: Inject the cream into pre-drilled holes at a slight downward angle so it sits against the base of each hole and migrates inward rather than running back out toward the face of the wall.
Sovereign DPC Injection Cream is used to treat rising damp in solid masonry walls where the existing damp proof course has failed or is absent. It is regularly used in older residential properties, period buildings, stone cottages, and commercial conversions where traditional DPC membranes were never installed. Damp proofing contractors, renovation builders, and property maintenance teams use it as a reliable and straightforward remedial treatment before replastering affected walls.

Key Properties
Cream format stays in drilled holes during application
Migrates through masonry capillaries after injection
Forms a hydrophobic barrier against rising moisture
600cc sausage fits standard sausage guns
Cleaner and less wasteful than liquid injection systems
Not suitable for: Not suitable for treating penetrating damp or condensation problems, which require different solutions. Will not perform correctly in saturated walls that have not been allowed to dry to an appropriate moisture level before treatment.
Before injecting, the wall should be as dry as conditions allow and free from loose render or plaster at the injection zone. Drill holes at the recommended centres and depth for the wall thickness in question, typically at a slight downward angle. Insert the sausage cartridge into a standard sausage gun, cut the nozzle tip, and inject a consistent bead of cream into each hole, working from the innermost point outward.
Once all holes are filled, plug them with mortar or a compatible filler and allow the cream to migrate and cure before replastering. Full diffusion takes several weeks depending on wall density and ambient temperature, so do not rush the replastering stage.
Check that the wall is free from saturated or actively wet conditions before starting work
Drill injection holes at the correct centres and to the appropriate depth for the wall thickness, angled slightly downward
Clear any dust from the drilled holes using a blower or brush
Load the 600cc sausage cartridge into a standard sausage gun and cut the nozzle to the correct aperture
Inject the cream fully into each hole, working from the back of the hole toward the face
Plug each hole with mortar or a suitable filler once injected
Allow the cream to migrate and cure fully before applying any new plaster or render to the treated area
How long does DPC injection cream take to work?
The cream migrates through the masonry capillaries over a period of several weeks after injection. The exact time depends on wall density, construction type, and ambient temperature. As a general guide, allow at least four to six weeks before replastering the treated area to avoid trapping moisture behind new plaster.
What gun do I need to use with the 600cc sausage cartridge?
The 600cc format is a standard sausage cartridge size, compatible with most skeleton sausage guns available from builders merchants. You do not need a specialist applicator, which is one of the practical advantages of the cream format over older pressurised liquid injection systems.
Can Sovereign DPC Injection Cream be used in stone walls?
Yes, it can be used in natural stone and mixed masonry construction, which is common in older and period properties. Injection hole spacing and depth may need to be adjusted to suit the irregular nature of stone construction compared to uniform brickwork, so check the manufacturer guidance for the specific wall type.
Sovereign DPC Injection Cream is a silane and siloxane-based formulation that works by diffusing through the pore structure of masonry after injection. Once cured, it lines the capillaries with a hydrophobic coating that breaks the upward movement of moisture through the wall. The cream consistency allows controlled application without the dripping and migration issues associated with low-viscosity liquid systems.
