external basement waterproofing

Tanking Specialists

Tanking Specialists are waterproofing contractors who specialize in external basement tanking. With the application of KOSTER's liquid membranes or self-adhesive sheet membranes our specialist waterproofers provide long lasting and cost effective tanking solutions. For private dwellings or large civils projects, we have the products and expertise you need.

internal basement waterproofing

Basement Waterproofing

Basement waterproofing can be applied from the inside, even if actively leaking. Our Waterproofing contractors will use a combination of KOSTER sealing slurries, waterplugs and renovation plasters to achieve a dry, healthy living space converting leaking basements into useful living space, without installing a sump pump.

chemical damp proof course

Damp Proofing Specialists

Our damp proofing specialists install fully functioning chemical DPCs (damp proof course) using KOSTER'S Crisin system. The damp proofing specialist drills boreholes in to the mortar course, then uses pressureless injection to penetrate into the pores within the wall, before finishing internally with salt blocking plaster.

resin injection

Resin Injection Specialists

Resin Injection is an effective way of sealing leaking cracks or restoring structural strength. With a wide range of KOSTER resins to choose from it is important to select a resin injection specialist who is knowledgeable and fully up to date with the most advanced injection products available and the latest injection techniques.

curtain injection pu gel

Gel Injection (curtain grouting)

If a basement has to be tanked from the inside, but the client (or local authority) wants to retain the original brickwork, our specialist waterproofers contractors inject a Polyurethane Gel forming an elastic waterproof layer on the outside of the structure, without needing excavation. This is particularly suited for the waterproofing of brick vaults.

roof waterproofing

Roof Waterproofing

Our roofing specialists use reinforced liquid membrane systems or TPO single ply membranes to waterproof flat roofs, podium decks, terraces and buried basement roofs. Liquid membranes are seamless, UV stable, and crack bridging. TPO membranes are extremely robust, with unrivalled life expectancy and up to 25 year guaruntee.
