Step 1

Excavation of the foundation trench, as near as possible in height and width to the dimension of the foundation. The surface of the bottom of the trench (bottom edge of the foundation) should be planar. Small, undulating bumps are accommodated by the Pecaform formwork and can remain. Backfills and holes must be satisfactorily eliminated using suitable filling material so that the soil is stable.

Step 2

U-shaped Pecaform ground beam elements that are suitably dimensioned in width and height are placed flush onto the soil. The joint area of the standard 2.4m long elements is overlapped by about 5-10cm and connected with tie wire. Fitting pieces, corner configurations and cross-over points are manufactured on site. To do this, a pocket knife is used to cut the foil and mesh shears(or similar tools) are used on the bar inserts. Smaller corner configurations can be shaped manually.

Step 3

The reinforcement system is now incorporated. It is secured to the Pecaform using bar spacers.

Step 4

Any required filling in of the formwork can now begin. The reinforcement system absorbs the force exerted by the pressure of the soil. Without reinforcement, filling is only possible up to a level of about 30cm.

Step 5

If it is not possible to fill up to around 20cm beneath the upper edge of the foundation, measures are required to support the formwork. The Pecaform formwork system offers suitable formwork girders for longitudinal reinforcement as well as distance spacers.

Step 6

The entire foundation can now be concreted in one pour.
