Preventing leaks on a terrace requires a systematic approach and the use of the right materials. At Immosegur, we offer you a step-by-step guide to effectively waterproofing your terrace, protecting your home from damp and possible structural damage.
The first step is to prepare the surface. Thoroughly clean the floor, removing dust, cement residue, paint, or any other debris. If possible, use pressurised water to remove stubborn encrustations. A clean surface ensures that the waterproofing products adhere properly and provides a solid foundation for the next steps.
Next, check all cracks and joints. These are the areas most vulnerable to leaks, so it is crucial to measure them and determine whether they need to be sealed beforehand. This planning will allow you to calculate the amount of material needed and decide on the most suitable waterproofing method based on the condition of your terrace and your budget.
The next step is to apply the primer, if required by the chosen product. The primer improves the adhesion of materials such as liquid polyurethane, epoxy resins or waterproof mortar, increasing the durability of the system and preventing premature leaks.
Next, apply the waterproofing material. You can choose from waterproofing paint, flexible sheets, liquid polyurethane or high-thickness resins. If you choose paint, apply several coats, allowing for drying time between coats. In the case of flexible sheets, make sure to glue them correctly with adhesive cement and reinforce joints, corners and drains with self-adhesive waterproofing strips.
Once the product has been applied, carry out a leak test. Cover the drains and leave water to accumulate for at least 24 hours to ensure that there are no leaks to the floor below. This test is essential to guarantee that the waterproofing works before laying new flooring or leaving the terrace as it is.
Finally, allow the waterproofing to dry completely before using the terrace. If you have applied paint or flexible sheets, regular maintenance will help prolong the protection, while more durable materials, such as epoxy resins or sprayed polyurea, can offer up to 20-25 years of effectiveness with minimal care.
By following these steps, your terrace will be protected against leaks and damp, keeping the structure of your home safe and functional. The key is to prepare the surface correctly, apply the right materials and reinforce critical points for long-lasting results.
