When Adding Floors Is Needed

Real estate in the city center and older districts with well-developed infrastructure is in high demand and highly valued. However, there is now hardly any available land for new construction or buildings suitable for demolition in these areas.

The only way to gain additional space is by adding floors to existing older buildings. Adding extra stories allows for additional usable space or a change in the building's functional purpose, and this can be done with minimal construction costs.

Our company will carry out preliminary engineering and site investigation studies, then reinforce the foundation and base in full compliance with applicable SNiP and GOST standards. Order a site visit from our specialist to find out whether adding floors to your building is feasible and to get a cost estimate for foundation reinforcement!

Approximate Estimate for Foundation Reinforcement

Our company uses the most advanced and progressive technologies for soil consolidation and foundation reinforcement. The final cost of the work depends on the soil type and the load-bearing capacity of the existing foundation.

If the survey shows that it's not possible to add floors while relying on the building's existing structure, an alternative may be to modify the structural design to redistribute the loads and transfer the weight of the additional floors onto independent foundations.

Nevertheless, it is almost always possible to carry out the reconstruction while meeting urban planning, aesthetic, economic, and social requirements.

We invite you to review the prices for foundation reinforcement. This page provides approximate pricing for various types of work per square meter. The final cost is calculated individually.

Type of Waterproofing	Price per m²
Removal of the Blind Area	₽1,600
Foundation Excavation	₽400
Drilling of Pits for Installing Pipe Packers	₽3,500
Diamond Drilling Through the Slab for Installing Pipe Packers	₽6,100

Frequently Asked Questions

What warranty do you provide for completed works?

The warranty for any type of waterproofing is 2 years. For injection waterproofing and foundation reinforcement, the warranty is up to 5 years.

Why is injection waterproofing needed?

Injection waterproofing helps to interrupt capillary flow and reduce the permeability of foundations, walls, and floor slabs. Injections of polyurethane gel (works on concrete), polyurethane resin (works on concrete and precast structures), and silicon-siloxane compounds (work on brickwork and precast structures) prevent moisture from being absorbed into the structural materials and improve the waterproofing properties of buildings.
