Services
Basement Waterproofing
We design and install comprehensive basement waterproofing systems that create dry, usable living spaces while preserving structural integrity. Our solutions include Type C cavity drain membranes with monitored sump systems, tailored to both new builds and historic properties. With specialist expertise in listed buildings and radon gas protection, we ensure compliance with building regulations while delivering insurance-backed guarantees for long-term peace of mind.
Damp Proofing
Our damp proofing services address rising damp, penetrating dampness, and condensation through precise diagnosis and targeted interventions. We implement specialist treatments that stop moisture ingress while maintaining breathability in traditional buildings. Our approach combines technical expertise with conservation principles to protect both modern and historic structures from the damaging effects of persistent damp conditions.
Flood Control
We provide flood protection systems that safeguard properties against surface water and groundwater ingress. Our solutions include waterproof barriers and drainage systems designed to withstand extreme weather events while maintaining property usability. With experience in vulnerable areas, we deliver tailored flood resilience strategies that protect both residential and commercial buildings from water damage.
Listed Building Preservation
Our specialist team delivers waterproofing solutions for listed buildings that maintain historical integrity while addressing modern performance requirements. We employ reversible techniques that comply with conservation regulations, preserving architectural features while preventing water damage. Our approach ensures structural longevity without compromising the character of heritage properties.
Timber Conservation
We restore and protect timber elements affected by damp-related decay and insect infestation. Our conservation methods combine traditional craftsmanship with modern treatments to extend the lifespan of historic and structural timbers. By addressing moisture sources and implementing protective measures, we prevent future degradation while maintaining the material's aesthetic and functional properties.
