What purpose do form ties serve in a concrete wall form?

A form tie is an accessory used in formwork, used to hold the concrete wall forms firmly against the lateral pressure of freshly placed plastic concrete. They maintain equal space between the forms which results in uniform thickness of walls.

What is tie rod in formwork?

Tie rods are temporary structures. Their primary function is to secure the formwork by holding them together during concrete pouring operations. They do this by clamping the formwork, preventing either side from bulging under the wet weight of the concrete.

What is a water stopper?

WHAT IS A WATER STOPPER OR WATER BAR? Water stoppers or water bars are flexible tape-like elements of a concrete structure that are embedded to prevent the passages of water or any fluids through concrete joints.

How far apart should snap ties be?

What is a concrete form tie?

Form ties (sometimes referred to as tie bolts) connect opposite faces of wall formwork to restrain the applied concrete pressures. They transmit loads in tension between stiff vertical and/or horizontal members associated with the main formwork.

Why is tie rod used in construction?

A tie rod or tie bar (also known as a hanger rod if vertical) is a slender structural unit used as a tie and (in most applications) capable of carrying tensile loads only. It is any rod or bar-shaped structural member designed to prevent the separation of two parts, as in a vehicle.

What is difference between water bar and water stopper?

Joints in direct contact with water need the protection of a waterbar. They are hydrophilic or impervious strips cast into the concrete at the joints to prevent the passage of water. Waterstops placed centrally provide efficient barrier to penetration of water from either face of slab or a wall.

Where do you put your water Stop?

Joints formed between adjacent concrete pours and where mechanical elements penetrate the concrete are the most likely points of water ingress into below-grade concrete structures. To prevent this from occurring, waterstops are commonly specified and installed at every joint in the concrete below-grade.

Where are water stop used?

Waterstops are mainly used for the waterproofing of below-grade concrete structures like tunnels, water treatment facilities, parking structures, water reservoirs, sewage treatment facilities, and marine structures.

How do you protect the water stop on a concrete tie rod?

We custom the water stop according to your concrete tie rod system requirement too. In concrete, clients also apply plastic caps on both ends of the water stop barries. The PVC adapter protects water stoppers in construction.
