Strip Seal is a mechanical device adapted for sealing an elongated gap formed between two adjacent road slab sections by providing a continuous support for vehicles crossing the gap while allowing the desired temperature responsive movement of the road slab sections. A single elastomeric neoprene rubber strip is secured to the adjacent roads sections on either side of the gap through heavy duty edge beams under a specially designed profile. The Strip Seal Expansion Joint is mechanically secured between the space straddling the gap guaranteeing water tightness and also preventing ingress of debris and corrosives which otherwise cold damage the superstructure and substructure components. The planned operative movement range of the Strip Seal Expansion Joint is from mm. Accommodates mm of movement Strip Seal is a mechanical device adapted for sealing an elongated gap formed between two adjacent road slab sections by providing a continuous support for vehicles crossing the gap while allowing the desired temperature responsive movement of the road slab sections.
Push the backer rod down into the joint with your hand. But what should be done with a crack that gets wider within the control joint itself? We have a concrete patio where no expansion rubber sealant was applied where it meets the foundation. Just called them. I see nothing as Tar strip expansion joint as a warranty. Like it? Hi Jeff.
Tar strip expansion joint. Why Expansion Joints in Concrete are Necessary
When it rains, sand rises up through the cracks and settles at the bottom of the driveway. October 28, at Expasnion. Hi Jeff. This is a highly automated solution for large quantities of the same type of joint. May 9, at PM. March 31, at PM.
An expansion joint or movement joint is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials, and vibration, or to allow movement due to ground settlement or seismic activity.
- The original ZipStrip control joint is a rigid polystyrene extrusion that creates a straight line, controlled crack on the surface of all on grade slabs.
- Expansion joints in our drive way are filled with black tar.

An expansion joint is a material placed in the cracks or joints between concrete slabs to protect Tar strip expansion joint slabs from cracking when they contract and expand as the temperature changes. This material acts as a shock absorber, absorbing the stress from the slab's movement. After a while, the expansion joint can dry out and won't absorb the stress as well as it once did. That's when cracks appear in the concrete slabs. When this occurs, it's time to replace the expansion joints.
Follow these instructions and you can do the job yourself. How to Install Weather Stripping. How to Repair a Deck. How to Repair a Leaky Roof. Sweep away any dirt and debris from the area. Dig out and remove all the old material that's in the joints with a putty knife. Flush out any remaining debris with a hose.
With a wet-dry vacuum, clean out the joints between the slabs very well. Apply a bonding adhesive, usually epoxy, into the joints with a brush. This will help the new material to bond to the old concrete. Let the adhesive dry for about 10 Tar strip expansion joint 15 minutes.
Don't leave the adhesive for any longer than that because it should be sticky to touch, not completely dry. Insert foam backer rod. This will be your new shock absorber.
Measure the amount Tar strip expansion joint backer rod you need and cut off a piece that's the right size. Push the strip into the joint with Heavy rain bondage putty knife, making sure to push it in all the way.
Cover and seal the joint. Apply a liberal layer of self-leveling urethane sealant. Block off the area so nobody walks on the newly placed joints until the sealant has dried.
ASPHALT EXPANSION JOINT Expansion/Contraction Control Joint. DESCRIPTION ASPHALT EXPANSION JOINT is the “original” expansion joint filler. It is composed of a blend of asphalts and mineral fillers formed under heat and pressure between two asphalt-saturated liners. QUIKRETE® Expansion Joint Strips (No. ) are made from resilient wood fibers to prevent damage during expansion and contraction of concrete. Weather resistant. Meets requirement of ASTM D 1/2 inch x 4 inches x 5 feet. Available in: 40 strips per carton. Dec 01, · Produced by Goodco Z-Tech, this video explains how to install strip seals on Series , Type C single cell expansion joints, which are used by the Ministry of Transportation of Ontario, as well.
Tar strip expansion joint. Keep them Watertight and Crack Resistant
July 4, at PM. Follow us on: Facebook Twitter. When I complained — they seemed to not care so much. Thanks for the reply. I purchased my home in What do you recommend? An expansion joint is a material placed in the cracks or joints between concrete slabs to protect the slabs from cracking when they contract and expand as the temperature changes. September 3, at PM. There is a crack between the step and slab. Typical specifications for a four-inch-thick slab are: . Download Brochure. Bagya says:. The Bitumen Mastic Pad we offer is well known for their attributes like optimum quality and reliability. Some are normal size some have grown wider and deeper.
Learn the exact step-by-step process to start and complete your dream bathroom makeover in 10 days plus exclusive video training! Keeping your joints watertight will prevent moisture from seeping under concrete pads and causing them to heave or sink.
Concrete is not an elastic substance, and therefore it does not bend or stretch without failure. This concrete characteristic is useful and at times harmful on some occasions. Its high compressive strength and hardness make the concrete useful for applications in construction. However, concrete moves during expansion and shrinkage, due to which the structural elements shift slightly. To prevent harmful effects due to concrete movement, several expansion joints are incorporated in concrete construction, including foundations, walls, roof expansion joints, and paving slabs.
