Prefabricated hollow walls<\/h1><\/div>Hollow walls are lightweight precast concrete walls constructed from two pre-cast walls, each \u00b16 cm thick. On site, these walls are filled with fresh concrete and provided with joint reinforcement to form one solid, watertight structure. These walls combine efficiency, strength and insulating properties and are ideal where full walls are impractical due to weight or lifting capacity, such as in basements or certain floors. <\/p>\n<\/div><\/div><\/div>

<\/div><\/div>Why choose prefabricated hollow walls?<\/h2><\/div>Hollow concrete walls combine efficiency, strength and ease of use.<\/p>\n<\/div>
- <\/i><\/span>\n
Light and strong: by being constructed with precast pre-cast and full concrete, the walls maintain their strength while the weight remains significantly lower than with full concrete walls.<\/p>\n<\/div><\/li>
- <\/i><\/span>\n
Waterproof: joint and reinforcement between the predals provide a solid and waterproof construction, making them perfect for basements and other wet environments.<\/p>\n<\/div><\/li>
- <\/i><\/span>\n
Prefabricated efficiency: the walls are fully prefabricated and quickly installed on site, saving time and labor and simplifying execution.<\/p>\n<\/div><\/li>
- <\/i><\/span>\n
Flexible application: suitable for basements, facades and floors where weight or lifting capacity may be a limitation. The hollow walls can also be insulated if required. <\/p>\n<\/div><\/li><\/ul>
