Send Photos on WhatsAppWhat we check before quoting expansion joint sealing
Most failed waterproofing jobs treated the stain, not the source. These are the points we check on every survey before we recommend a system or a price.
Sealant adhesion & hardening
Old sealant tested for adhesion and elasticity; hardened, UV-damaged sealant has lost the ability to move and must come out.
Joint width & movement
Joint width and expected movement decide the sealant and the joint profile, so the new joint is not overstressed.
Backer rod & depth
Correct backer rod and sealant depth checked — a joint filled too deep or bonded on three sides tears itself apart.
Joint covers
On roofs, podiums and car parks, wide joints may need a pre-formed joint system or cover plate rather than sealant alone.
