What Can I Do For You?
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. this material acts as a shock absorber, absorbing the stress from the slab's movement.
expansion joints are placed in concrete to prevent expansive cracks formed due to temperature change. concrete undergoes expansion due to high temperature when in a confined boundary which leads to cracks. expansion joints are provided in slabs, pavements, buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures.
concrete isolation joints, or expansion joints, separate or isolate the concrete from other parts of the building structure like walls, footings, columns and piers. a concrete expansion joint is also used to separate a concrete driveway or patio from a garage slab,
the latest innovation in expansion joint repair is the installation of rubber-like sealing strips. use of a flexible material, simply pressed into place makes expansion joint repair diy-easy. no cure time, no mess to clean up, no technique needed to get a great-looking result. the easiest to install of these is trim-a-slab.
a slab will continue to shrink, and widen the control joint, for years, although most of the shrinkage takes place within the first year and especially within the first 90 days. once the joint is cut into place, the joint itself is ready to do its job. the joint can then be left as is, sealed, or filled. sealing or filling should be put off as
maximum joint spacing should be 24 to 36 times the thickness of the slab. joints should be spaced about 10 feet and a maximum of 15 feet. when using joint groove for contraction joints, the joint should be a minimum depth of ¼ thickness of the slab. saw-cut joints should be done within 4 to 12 hours after the concrete has been finished.
an expansion joint is a common source of moisture and dangerous soil gases like radon, emecole metro 85-90 seals the joint while still allowing slab movement. warehouse floors: expansion and control joints in warehouse floors often catch the small wheels of carts. emecole metro 85-90 self levels in the joint and it can be shaved smooth for a
expansion joints should always be created where old concrete meets new concrete. patios, sidewalks, driveway slabs, etc. poured up against an existing foundation are excellent examples of places to create expansion joints. foundations do not “float” during the year due to humidity or temperature changes while slabs
high performance expansion joint fillerboard, for concrete slab construction and brickwork joints, which is supplied pre-cut to depth of sealant for controlled void formation and easy removal. robust, non-absorbent with excellent recoverability of 100% from 50% compression, low load transfer, non extruding and resistant to attack by most acids and alkalis.
fiberflex® fiber expansion joint is a joint filler made from proprietary wood fiber blend of treated wood fibers and additives which yields flexible, easy -to-handle boards. it is used to prevent damage during expansion and contraction of concrete. this product is weather-resistant and meets the
use sakrete concrete expansion joint, an innovative and flexible material for concrete expansion and isolation joints. packaged in 50 foot lengths. use wherever concrete expansion joints are applicable: slabs, drives, sidewalks, isolation joints and in all standard concrete construction such as highways, runways and parking garages.

one of the common ways to repair concrete expansion joints involves some basic tools and a lot of time. use a scraping tool, like a 5-in-1, to scrape out the old concrete expansion joint filler. vacuum out the concrete expansion joints. use a caulk gun with your filler of choice and refill the joints. scrape the sides and top of the joints to
description asphalt expansion joint is composed of a blend of asphalts, vegetable fibers, and mineral fillers formed under heat and pressure between two asphalt-saturated liners. it is waterproof, permanent, flexible, and self-sealing. fibre expansion joint is composed of cellular fibers securely bonded together and uniformly saturated with asphalt to assure longevity.
contraction joints provide for movement in the plane of a slab or wall, and induce cracking caused by thermal shrinkage at preselected locations. one of the most economical methods for making a contraction joint is by simply sawing a continuous cut in the top of the slab with a masonry saw.
expansion joints in concrete pavement are also seldom needed, since the contraction joints open enough (from drying shrinkage) to account for temperature expansion. the exception might be where a pavement or parking lot are next to a bridge or building—then we simply use a slightly wider isolation joint (maybe ¾ inch instead of ½ inch).

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. it is waterproof, permanent, flexible, and self-sealing. uses. asphalt expansion joint can be used in 80% of all control joint applications.
geolift can help to lift existing concrete surfaces and fix those problem areas around your house with much less labor. geolift works for driveways, sidewalks, patios, garage floors, even pool decks. and yes, it is a foam, just like your beloved spray foam! geolift works in three steps. the first step is to drill holes in the problem concrete.
fiber expansion filler board. rockmax flexiboard is an expansion joint filler board use for filling expansion concrete joints. the product is manufactured from cellular fibers and saturated asphalt. it provides very good flexibility and recovery properties with non-extrusion conforming to astm and aashto standard. read more
moving cracks and expansion joints should be injected with sealboss 1570 flexible water-stop. hairline cracks and dry cracks can be sealed using 1400 lv-resin line. some problems are solved by using a combination of products. a major water leak through an expansion joint for example, can be initially stopped with 1510 water stop.
slabs where used to form an expansion joint in in-situ concrete, fosroc fibreboard shall be placed against the shuttering on the concreting side before the pour begins. copper nails may be used to prevent displacement in joints in suspended slabs. alternatively, fosroc fibreboard may be bonded to the existing

because expansion joints are an important factor in maintaining the integrity of concrete and asphalt surfaces such as roads, sidewalks and driveways, expansion joint repair is a key factor in keeping these surfaces from cracking and breaking up.expansion joints, like other construction materials, eventually need to be repaired or replaced.
