The SITURA joint waterproofing system has many distinct technical advantages over other types of expansion joints such as bellows type joints, prefabricated metal joints, bunched up membrane or membrane over a backer rod type joint. Here are eight of them for consideration:
- Provides a flat zero profile waterproofed joint, without obstructing the flow of water across the joint.
- System is custom tailored to specific site conditions, including difficult areas to detail and waterproof such as; inside and outside corners, “T” joints, “X” joint intersections, curved joints, multilevel joints, etc.
- Flat expansion joint system has the capacity to move in all three planes simultaneously, i.e. horizontally, vertically and transversely, while remaining flat.
- No complicated calculations are required since the joint is flat and in the plane of expansion/contraction. The only measurements required are clear center to center distances between fixed points.
- In roofing, flat expansion joint material is installed between the roofing plies of BUR and Modified Bitumen in a flood coat of asphalt. Result is that the waterproofed joint is an extension of the actual roof membrane, with no flashing plies or special detailing required.
- Flat expansion joint system forms a continuous uninterrupted waterproofing solution from the start of the expansion joint to its termination, which can be in a different part of a building for example underground. The zero profile of SITURA expansion joints allows it to traverse across any building surface from inside to outside, above or below grade.
- Expansion joint waterproofing is made continuous with the same expansion capability along its entire length. Any seaming in the SITURA joint waterproofing is as flexible and has the same elongation as the base expansion joint material itself.
- Seams found in the expansion joint system are all vulcanized under factory-controlled conditions, (site seaming is possible using a special portable vulcanizing press system). The vulcanization process provides the best method of joining pieces of joint waterproofing material. No glue, tape or caulking is used, therefore a watertight maintenance free waterproofing solution.
Any waterproofing system. Any condition. Situra = watertight expansion joint integrity.
