A construction joint is where one form of construction stops and another starts – thus forming a weak path for water to enter through. It is integral that specialist products are used to waterproof areas.
Newton have a comprehensive portfolio of waterbars for the waterproofing of construction joints between elements of the reinforced concrete structure:
Products For Waterproofing Construction Joints
Newton 301 EasyProof is a unique coated metal water bar which is secured to the reinforcing steel prior to the concrete pour. This results in a physical barrier to water with the special coating gripping to the concrete so as to remain completely watertight even after concrete shrinkage.
Newton 303 PolyProof is a range of swelling (hydrophilic) waterbars that are suitable for all types of joints such as the kicker, slab pours to sheet piles, compression, settlement and movement joints. It seals gaps in construction joints by swelling up to 400% its original size. In addition, it can be used as the water bar in settlement or compression joint.
Construction joints can be further reinforced with a band of Newton 106 FlexProof to provide a combined waterproofing approach. It can be applied to the construction joint using a trowel or squeegee and is rainproof in minutes. FlexProof-X1 provides a continuous highly flexible membrane that is resistant to water pressures of up to 2 bar (20m) over construction joints of up to 0.25mm.
“We used almost the full range of System 300 products for the “Hotel Football” project next to Manchester United’s Old Trafford ground and found them to be easy to install and reliable, and especially useful in overcoming difficult construction detailing” – Bill Hockey, Trace Basements, Newton Specialist Basement Contractor (NSBC)
