Main Contractors
Main contractors managing commercial and industrial construction or refurbishment programmes need a system supplier who can specify correctly, supply reliably and coordinate installation through an applicator they can trust. Forti Nova provides exactly this: direct manufacturer-backed supply, pre-project technical specification, and coordinated delivery via trained approved applicators — reducing the risk of system incompatibility, warranty disputes and programme delays.
Sector Pressures & Constraints
Main contractors are commercially responsible for the performance of every element of a building programme — including the roofing and waterproofing sub-contract. A waterproofing failure during the defects liability period creates a warranty claim, potential legal liability and relationship damage with the client. Main contractors need to specify systems with clear manufacturer backing, documented applicator qualifications, and written warranties that can be passed through to the building owner. Selecting the wrong system — or the right system applied by an untrained installer — creates avoidable commercial risk.
Refurbishment Context
On refurbishment programmes, main contractors encounter existing roofing and waterproofing substrates that vary in condition, material type and compatibility with overlay systems. Correct substrate assessment before specification is critical. Forti Nova provides pre-project technical assessment to confirm system suitability and substrate compatibility, reducing the risk of specification error and on-site programme disruption. On new-build schemes, early technical engagement allows systems to be incorporated into the specification package with full coordination between structure, envelope and drainage design.
How Forti Nova Works with Main Contractors
Forti Nova operates as a specialist systems supplier to main contractors — not as a roofing sub-contractor. We supply Liquid Rubber and Prokol systems with full manufacturer backing, provide technical specification support at tender and pre-construction stages, and coordinate trained approved applicators for the installation phase. We work with the main contractor's supply chain team, commercial managers and project managers to ensure the correct system is specified, priced and delivered within the programme.
