Reinforcement of jumpers, slots and arch nodes

Installation of long spiral rods arranged according to the project above door and window openings is a quick and easy way to create or repair brick (block) arched lintels in buildings. Prestressed stainless steel rods can be used in existing brick (or stone) masonry to form a reinforced brick (gas block, concrete block, stone) bridge over a flat level or curved vault.

Failure of jumpers occurs for a number of reasons. Shallow or flat brick arches can fail due to insufficient support on either side of the arch, concrete lintels tend to rotate, wood warps from drying or moisture, and metal lintels can degrade over time as rotting or corrosion begins.

There is nothing unusual in the fact that an old wooden or metal window frame forms an independent lintel that helps support the masonry above. When these load-bearing structures (windows and doors) are replaced with less durable PVC blocks, the support from this lintel is lost and the masonry can begin to crack as it sags.

Where lintels are bowed or damaged, this method of strengthening and repairing prefabricated arch lintels can be supplemented by the provision of metal anchors installed vertically up through the arch into the reinforced beam masonry area. Where cracks have appeared above the opening, they can be stitched with shorter ties, and the cracks can be filled with injections of a special low-viscosity filler.

The practice of using technologies to solve problems

2 ways to solve problems

You can contact the company and get a turnkey restoration solution by going through following stages:

  • First contact and consultation
  • Visit of a specialist for inspection and measurements
  • Development, presentation and mutual technical discussion decisions
  • Signing of the contract for the provision of services
  • Carrying out repair and restoration works
  • Post-project monitoring (if the service is included in the contract)

You can carry out the work yourself, having received the engineering project and the necessary materials on hand, after passing the following stages:

  • First contact and consultation
  • Obtaining the necessary information for project development decisions
  • Development, presentation and mutual technical discussion decisions
  • Handing over technical cards and conducting consultations on the independent implementation of repair and restoration works
  • Signing of the contract for the supply of materials
  • Forwarding or transfer of all necessary tools and materials
