Every concrete structure moves. Thermal expansion, shrinkage, live loading, ground movement and long-term creep all cause dimensional change. Movement and expansion joints accommodate that change while keeping the structure watertight, safe to traffic and structurally intact. When the joint fails, water penetrates the structure below, deck reinforcement corrodes, and the failure quickly becomes far more expensive than the joint itself.
CRS delivers movement and expansion joint works across the full range of applications. Replacement of failed bridge deck joints under traffic management. Refurbishment of car park deck joints as part of wider deck programmes. Movement joint installation and resealing in commercial and residential buildings. Waterproofing joints in tanks, basements and below-ground structures. Perimeter and abutment joint sealing across a range of structure types.
Joint failure is often the visible symptom of a wider problem. Water tracking through a failed joint corrodes the deck reinforcement, spalls the concrete below, and shows up as staining or falling debris long before the joint itself is inspected. CRS treats joint work as part of a wider structural assessment where appropriate, ensuring the underlying damage is addressed alongside the joint replacement.
Materials are selected from approved system suppliers including Sika, Weber and Mapei. Joint systems are matched to the movement range, traffic loading, waterproofing requirement and expected service life. Elastomeric asphaltic plug joints, modular expansion joints, mechanical finger joints, saw-cut sealant joints and buried expansion joints are all delivered against the specification the structure requires.
