Costa del Sol enjoys over 300 days of sunshine, but when the rain arrives it arrives in volume. Annual rainfall is concentrated in just a few intense weeks, and slopes, foundations and pools take the hit.
A modern drainage system is no longer optional for a luxury villa — it is the single most important investment for protecting your property over decades.
Why traditional gravel drainage fails Gravel drainage was the standard for decades, but in modern construction it shows its age: heavy logistics, clogging, settling, and significant excavation work. On hillside properties typical of Marbella and Estepona, traditional systems often fail within 5–8 years.
The DrenaFast™ alternative DrenaFast™ replaces gravel with an engineered drainage tube wrapped in a high-flow geotextile filter. The result: faster install, less excavation, no gravel logistics, and a stable drainage zone that lasts.
Where it matters most - Foundations of new villas - Retaining walls on slopes - Pool perimeters and terraces - Garden zones with poor soil drainage
Cost vs damage A properly engineered drainage system represents 1–2% of construction cost — and prevents water damage that can reach 15–20% of the property value.
