Terrace planner - planning in detail

Subsurface condition

Natural soil

If the subsoil is insufficiently compacted, the soil must be excavated accordingly. The total depth of the excavation can be up to 80 cm. Fill in the crushed stone bed or similar, pour a bed of chippings on top and level off with a 1.5 – 2 % slope. Then lay out concrete stone slabs as supports for the substructure ledgers. The height of the substructure ledgers can be selected between 20 and 75 mm and with selected profiles, downward fastening can be dispensed with.

2 = WERZALIT substructure
3 = Fixing substructure
4 = WERZALIT rubber pads

5 = Concrete slab
6 = Weed fleece
7 = Stone chippings bed, approx. 5 – 15 cm
8 = Ballast bed, approx. 25 – 65 cm

Concrete floor

Concrete floors must be load-bearing and have a slope of at least 1.5 – 2 % to prevent waterlogging. The substructure ledgers are laid on the raw concrete slab and underlaid with rubber pads 100 x 100 x 5 mm so that water accumulating underneath can run off unhindered.

2 = WERZALIT substructure

4 = WERZALIT rubber pads
5 = Concrete slab

Roof terrace and flat roof with waterproofing membrane

To protect the waterproofing layer from mechanical damage, the substructure must be underlaid with rubber pads 100 x 100 x 5 mm or sections of a building protection mat. To prevent a chemical reaction between the rubber pad and the waterproofing membrane, a separating layer of weed fleece or PE foil must be inserted. The substructure bars must not be fastened downwards through the sealing sheet! To achieve sufficient stability, a frame construction or cross battens should be used.

Compensation of level differences

To compensate for larger differences in the level of the subfloor, we recommend the use of stilt supports. These are available in different heights and can be adapted to the conditions with millimetre precision.

Installation types

PREMIUM solid planks from WERZALITcan be laid in ship’s bond or in parallel bond.
For the continuous joint when laid in parallel bond, we can supply high-quality joint cover profiles made of aluminium on request. This means that even larger gaps can be covered without any problems.

Installation method:
1 = ship’s bond
2 = Parallel bond

Joint cover profile made of aluminium, two-part

Separation or expansion joints in partial areas as well as mitre joints can be covered with the 2-part aluminium joint cover profile. For this, the joint size must be at least 55 mm wide according to the width of the basic profile.

Aluminium joint cover profile

If the two-part joint cover profile is not possible, the aluminium joint cover strip can be used

Edge trim and wall connection profiles

Give your terrace the right edge trim and wall connection. Choose between modern aluminium or WPC to match the PREMIUM solid planks and give your terrace the perfect visual finish.

Edge profiles

Edge trim profile aluminium, two-part

Elegant side edge over the entire height. The two-part aluminium edge profile is available in three anodised colours to match any PREMIUM solid plank from WERZALIT.

Aluminium edge trim

For covering straight or sloping profile cut edges and for reinforcing heavily used edges and transitions.

Aluminium edge trim

For covering the front of profile cut edges on curves.

Edge trim profile WPC

For covering the front of profile cut edges on straight edges or curves. Available in matching colours to PREMIUM solid planks.

Wall connection profile

Wall connection profile aluminium

With the wall connection profile from WERZALIT you create a defined connection to the masonry. The wall connection profile offers sufficient space to accommodate linear expansion and bridges the joint to the wall former.
The integrated oblong holes ensure sufficient rear ventilation of the entire substructure.

Shapes (for checklist)

Give your terrace the right edge trim and wall connection. Choose between modern aluminium or WPC to match the PREMIUM solid planks and give your terrace the perfect visual finish.
