The owner decides for his favorite adjustment of the building. Therefore we draw the ground plan in real scale on the ground, to get a living impression of the future building and its adjustment.
The strip footing has proved its value on La Palma Island. It runs under the exterior walls and will be connected with the roof by corner columns. On request we also build a bed-plate footing, which is very popular in other regions on earth. But you should take into account, that this footing type it is no ideal solution for the natural conditions on La Palma Island.
All rods of the footing will be connected with copper wire and properly grounded.
The horizontal moisture barrier between the footing and the brickwork is a very important part of the construction. We developed a special technique which has been approved for many years and prevents all rising damps.
The Spanish law for energy efficiency requires certain standards for new buildings. Therefore it is necessary to use either bricks of 29 cm (11.42 in) or a double brick wall with cavity. Our experience shows that 29cm-bricks are the better way: they provide a comfortable room climate and got a better price-value relation.
Contacto builds roofs following the traditional German roof structure: Batten, counter-batten, moisture barrier, tiles etc. (see sketch) Only a breathable roof is able to let the entering moisture (caused be wind, storm or other natural phenomena) pass out again.
The water-resistance of a flat roof is achieved by its slope, which allows the water to drain off. We use an isolation based on rubber. It has a water resistance warranty of ten years, provided by an insurance company. The thermal insulation will be made by rock wool, the humidity insulation by a diffusion house wrap.
After finishing the shell construction, we plan together with the future owner the distribution of headlamps, switches and sockets.
Together we make the designs of bathroom and kitchen. You can choose tiles, bathroom fittings and other items from one of our local suppliers or even order them from foreign distribution companies.
A proper window should be not only water and wind resistant, it also needs to be breathable - to guarantee a constant air exchange. That's why we cooperate with several distribution companies from Germany. Furthermore we can offer you tailor-made windows made of different materials, such as wood, plastics or aluminum.
We use breathable plastering for a comfortable room climate. This kind of plastering allows a high weather resistance by coevally aeration of the interior rooms.
It's essential to isolate the floor screed against moisture and heat loss. For waterproofing we use waterproof foil and for thermal insulation Styrodur (5 cm). Another possibility with an additional benefit could be a swimming screed, which is a second screed, isolated from its surrounding structure. This prevents outdoor temperature changes from being transmitted to the floor.
You've got free choice! We are able to lay all kind of tiles and however you prefer: linear, diagonal or with patterns.
We use either standard interior doors or tailor-made doors, made by our in-house carpenter.
SFor both interior painting and exterior painting we strongly prefer the use of breathable colors. This facilitates, together with the breathable plastering, a comfortable and ideal room climate. Wood will be treated with a water based wood preservative.
We do not only build houses, we are also highly experienced in creating outdoor facilities as terraces, pergolas, swimming pools, barbecues, carports, natural brick walls, outdoor showers, outdoor kitchens, fences, gates etc.
