Services
Asphalt Roofing
Asphalt roofing provides a durable, seamless waterproof layer for flat roofs. Our systems last 4070 years, resisting wear and simplifying repairs. Ideal for domestic and industrial properties, this solution ensures long-term protection against leaks and weather damage.
Asphalt Tanking
Asphalt tanking creates impermeable barriers in basements, preventing water ingress. Applied to walls and floors, it ensures structural integrity for decades. Concrete or brick coverings protect the asphalt layer, guaranteeing permanent waterproofing for subterranean spaces.
Asphalt Flooring
Asphalt flooring offers versatile solutions for damp-proofing and levelling surfaces. Suitable over concrete, quarry tiles, or failed DPCs, it suppresses dust and supports various floor coverings. Grades vary to meet residential and commercial requirements.
