Services
Damp Proofing
Our damp proofing solutions address rising damp through DPC injection and replastering. We use specialist barrier creams and renders to prevent moisture ingress, ensuring structural integrity and compliance with British standards. Ideal for residential and commercial properties.
Basement Waterproofing
Basement waterproofing employs cavity drain membranes and Koster systems to create watertight spaces. Designed to BS:8102(2009) standards, our methods protect against groundwater ingress in heritage and modern buildings, including luxury developments.
Dry Rot Treatment
Dry rot treatment involves targeted chemical applications and removal of infected materials. We restore structural timber integrity using epoxy resins and fungicidal treatments, preventing regrowth while preserving original frameworks in affected properties.
Cavity Drain Membrane
Cavity drain membranes channel water to drainage systems, offering an alternative to traditional tanking. As Delta-approved installers, we ensure compliance with building warranties, providing reversible solutions suitable for listed buildings and basements.
Replastering
Post-damp treatment replastering removes contaminated materials and applies salt-resistant renders. Our specialists ensure walls are ready for decoration, preventing recurring damp issues through breathable, durable finishes tailored to property requirements.
