Below-ground applications

Waterproofing capping beams ensures continuity with adjacent retaining walls. Systems can be installed before or after concrete pour to create a durable, integrated barrier against groundwater ingress.

Waterproofing footings requires correct placement within the formwork. Choose a full waterproofing membrane system for active protection or a damp-proof membrane (DPM) for moisture resistance on low-risk builds.

Waterproofing ground beams protects vulnerable connections to slabs and walls. Depending on site sequencing, membranes can be pre-applied in formwork or applied once the beam is poured.

Lift pits are especially prone to water ingress as the lowest point of the building. Our range includes re‑applied membranes to slab and wall formwork or post-applied to precast, masonry and in situ walls. 

Membranes are applied directly to secant or steel sheet piles after excavation, forming a barrier before concrete walls are cast – securing waterproofing continuity in below-ground structures.

From new concrete slabs to alterations to existing slabs, we offer pre-applied and remedial membrane systems to ensure reliable waterproofing and continuity across structural junctions and penetrations.

From in situ pours to masonry and precast panels, our wall waterproofing systems adapt to site conditions, sequencing and access, offering reliable performance below ground.
