Sierra Build Costa del Sol Renovation

The Beauty of Sotogrande 🌿

There is something truly special about the atmosphere of Sotogrande — elegant, peaceful and surrounded by nature. A place where Mediterranean lifestyle meets timeless architecture.

Beautiful colonial-style villas, lush gardens, palm trees and quiet streets create an atmosphere of effortless luxury and privacy.

Sotogrande is not simply a place to own a beautiful property — it is a lifestyle. Slow mornings, warm evenings and the unique feeling of being somewhere truly special.

Sotogrande — where Mediterranean elegance meets timeless luxury. 🌴🏡✨

💧 Proper waterproofing starts with a properly prepared base.

On this project, the previous construction team had not created the correct slope for proper water drainage. We corrected the base by installing a new screed with a minimum 3 cm slope and properly forming the corners and junctions between the walls and the screed.

The surface was then waterproofed with 2 coats of Sika Sikalastic®-612 — a high-quality liquid waterproofing membrane that creates a seamless, durable and watertight layer.

Now the water flows naturally towards the drain, with no water accumulation. 💦

We fix the problems, do it properly, and build for the long term. 🇪🇸

Professional Waterproofing & Drainage System for Large Raised Planters

We professionally prepare and protect large exterior raised planters, garden areas, and landscaped spaces, ensuring reliable waterproofing, drainage, and long-term protection of the structure.

The process begins with the preparation of the concrete surface, followed by the application of three layers of Sika waterproofing system to create a strong and durable barrier against water pe*******on.

After the waterproofing is completed, a special drainage plastic membrane is installed along the walls. Protective fixing profiles are securely attached using screws and wall plugs.

Between the profile and the wall, we apply a high-quality waterproof silicone adhesive/sealant, creating a tight and watertight connection. All joints and fixing points are carefully sealed to prevent water from penetrating behind the membrane or reaching the structural walls.

This carefully sealed system ensures that water is directed into the drainage layers and into the soil, rather than running down or penetrating the walls of the structure.

At the bottom, we install a high-quality geotextile/eco-fabric membrane. This layer allows water to pass through while retaining the soil and preventing soil erosion and blockage of the drainage system.

A layer of expanded clay (LECA) is then placed over the geotextile to create an efficient drainage and aeration layer. Another layer of geotextile is installed above the expanded clay before the planter is filled with high-quality soil.

The final result is a professionally constructed planting system designed for thuja, shrubs, trees, and other landscaping plants, providing efficient drainage while protecting the building structure from moisture and water damage.

Professional waterproofing. Professional drainage. Long-term protection.

We provide high-quality solutions for large exterior planters, terraces, gardens, retaining structures, pools, and other areas exposed to water and moisture.
