Install a new chemical DPC efficiently, economically and at scale with our 5 litre buckets and kits! Ideal for larger rising damp projects. Please Note: The kit option includes 1 x 5L PermaSEAL PRO Cream as standard.


DPC Cream 5 Litre Buckets

PermaSEAL PRO DPC Injection cream provides permanent protection against rising damp with 80% active ingredients (silane). Our five litre buckets of high strength cream are ideal for larger projects. It is suitable for chemical DPC installation in walls of various types, including substrates with high saturation levels.

With deep penetration and minimal mess, our high-performance DPC cream forms a reliable horizontal barrier to block water and ground salts. The injection cream is available either as individual buckets or as a convenient kit.

5 litre DPC Injection Kit contents

We’ve made our 5-litre DPC buckets available as part of a kit with everything you need to install a new chemical DPC for larger projects, including:

  • 1 x PermaSEAL PRO High Strength DPC Injection Cream 5 Litre
  • 1 x Economy DPC injection Unit with lance
  • 1 x 12mm x 300mm SDS Drill Bit

5 Litres of PermaSEAL PRO DPC Cream will cover approximately 50 linear metres of single skin (110mm, 4.5") brickwork or 25 linear metres of double skin (220mm, 9") brickwork.

Using our 5 litre DPC injection kits

Our five litre PermaSEAL PRO kits are ideal for larger projects, delivering our high performance cream efficiently with minimal mess.

  • Locate a mortar joint at least 150mm above external ground level. In case of solid floors, insert the damp proof course as close to the internal floor level as possible. The internal and external DPC levels must be at the same height.
  • Once you’ve selected the mortar joint, drill 12mm diameter holes horizontally in the mortar bed at centres no greater than 120mm. The depth of the hole required should be 20mm less than the wall thickness e.g. if the wall is 115mm thick then drill a 12mm hole to a depth of 95mm.
  • Vacuum the dust from the holes.
  • Pour the PermaSEAL PRO DPC Injection Cream into the injection unit and pressurise.
  • Inject the DPC Cream into each hole, put the injection lance into the back of the hole and inject slowly. Withdraw the lance as the cream fills the hole. Stop approximately 10mm from the outside edge of the hole.
  • As soon as possible, plug the remaining 10mm hole with mortar or insert a DPC Injection Plug. Closing off the surface of the hole will aid the dissipation of the actives along the mortar course.

With all Damp Proof Course injections, you need to re-plaster salt-contaminated walls strictly adhering to specification. Please ask for our recommended re-plastering spec or refer to our guide to re-rendering after DPC installation.

Refer to the datasheet for more detailed installation instructions along with application rates and requirements.
