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.

Robust carpark waterproofing membranes engineered to resist traffic stress, thermal extremes and water ingress. Find systems for asphalt or concrete overlays – all compliant with New Zealand performance standards.

Allco deck membranes suit concrete and timber decks, with solutions for zero-fall podiums, low-slope roofing and high-performance finishes using systems with proven in-service performance.

For re-roof projects, Allco has a range of systems that enhance thermal and acoustic performance and restore weathertightness. Talk to us about the right approach for an existing roof.

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.

Allco planter waterproofing systems combine durable membranes with optional root barriers, ensuring long-term protection against leaks and root damage in both low-risk and complex planter conditions.

Allco podium membrane solutions deliver long-term waterproofing performance for suspended slabs, supporting continuous, durable finishes whether tiled, planted or paved, including certified options for zero-fall installation.

Allco roofing membranes exceed NZBC standards and support a wide range of construction types, substrates and finishes, including warm, green and low-slope roof systems.

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.

Protect slab-on-grade builds from rising moisture with the right membrane system. Choose damp-proof membranes for low-risk sites or waterproofing systems where greater protection is required.

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.
