The monolithic foundation system (the SPWS CONCRETE SLAB-FOUNDATION SYSTEM) permanently solved all issues related with ground instability as well the slab cracking arising from the differential settlements of the foundations.
Our patented technologies (including the SPWS SEMI CONTINUOS CONCRETE SYSTEM) have several advantages such as:
The high speed of execution with a significant reduction of tasks, from earthmoving to the reduction of materials needed for bases, sub-bases and drainage of foundation soils;
Works concluded 40% faster and 30% cheaper.
Efficiency up to 45,000 m2 / 8h shift / by Slip Form and up to 1200 m2 / 8h shift / by Vibrating Straight Edge
The reduction of the overload caused by the landfill on the natural ground from 1800 kg / m3 to 30 kg / m3 when replacing the conventional bases and sub bases;
The huge reduction earthmoving - the preparation of the site work, removal of topsoil and the opening of the box in the ground are the only actions required;
The joint opening without mechanical intervention;
Effective tightness of joints preventing liquid infiltration to and from the base and eliminating the "pumping" phenomenon;
The no need for sealing the joints;
The possibility of using light equipment (vibrating straight edge) in the construction of the pavement, which can be decisive in cases works in remote locations or for warehouses and factories;
The no need to reinforce the slabs
The concrete without any added fibers;
Slabs with more than 6m long
Construction environmentally friendly;
Reduced or almost nonexistent maintenance;
OUR TECHNOLOGY ALLOWS:
a) cheaper works – 30%
b) faster works – 40%
c) better construction decreasing expenses
d) more ecological and cleaner works
e) use of high resilient concrete, unreinforced and without fibers.
f) joints that have no need to be sealed.
g) ensure strict flatness, with a maximum deviation of 1mm
h) allows the use light equipment in the building process
i) allows to waive the use of piles on soils with very low CBR or K
OUR TECHNOLOGY STILL ALLOWS:
To reduce very significantly overloads on the natural ground.
To predict on a long-term basis the conduct of the base and dimensioning the slabs accordingly.
Build the concrete slab directly over the E.P.S (high density expanded polystyrene) base
Transfer effectively the loads on a slab to all the adjacent slabs.
Obtain a continuous pavement that accepts all differential settlements of the natural ground.
Increase the space between joints and reduce the width of the joints.
Prevent water seepage and / or contaminants to the base, avoiding all the phenomena of "pumping".
Excellent construction efficiency over traditional systems (load transfer bars (dowel bar) etc.).
To reduce very significantly all tensions in the plastic concrete shrinkage phase.
Decrease construction costs when compared to traditional concrete or asphalt construction systems.
OUR TECHNOLOGY ALLOWS:
The reduction of the overload caused by the landfill on the natural ground from 1800 kg / m3 to 30 kg / m3 when replacing the conventional bases and sub bases;
The joint opening without mechanical intervention;
The quickness of construction arising from a significant reduction of earthmoving and avoiding compacted bases layers construction and a layer of lean concrete
The possible use of light equipments (vibrating straight edge) for concrete pavement construction that can be of the utmost importance in remote areas without road access and for warehouses and factories.
The shortening of construction deadlines and decreasing construction costs versus traditional construction systems.
FOR ALL THESE REASONS WE CAN ENSURE THAT IT IS THE BEST TECHNOLOGY IN THE WORLD
