Cada zona de Barcelona tiene sus propias patologías. Estas son las que detectamos más en Castelldefels:
Corrosión marina en fachadas de la zona costera — el salitre deteriora especialmente las instalaciones.
Piscinas con grietas y fugas estructurales — en viviendas con más de 20 años.
Cubiertas planas sin mantenimiento — en bloques de los años 80.
Castelldefels fue un pueblo agrícola en torno a la iglesia y al castillo, en el llano entre el macizo del Garraf y el mar. Desde mediados del siglo XX la playa atrajo segundas residencias: bloques de apartamentos y casas junto al paseo marítimo y en La Pineda, entre pinares, y urbanizaciones de chalets en las laderas del Garraf, como Bellamar y Montmar. Con los años muchas pasaron a ser primera residencia, y el centro y los barrios cercanos se completaron con bloques de pisos y promociones más recientes.
En Bellamar y Montmar muchas casas están en pendiente: inspecciona muros de contención, drenaje del terreno, grietas en la estructura y accesos. Cerca del mar, la inspección comprueba barandillas, armaduras de balcones y carpinterías expuestas al ambiente salino, y en la zona llana próxima a la playa mide las humedades en plantas bajas y sótanos. En bloques de apartamentos que nacieron como segunda residencia, pregunta for la ITE, las derramas aprobadas y el estado de terrazas y cubiertas, y comprueba que la vivienda está preparada para usarse todo el año.
Bellamar — Urbanización de chalets en la ladera del Garraf, con calles en pendiente. Inspecciona muros de contención, drenaje del terreno, cubiertas y posibles grietas estructurales.
Montmar — Chalets de distintas épocas en la parte alta de la montaña, con parcelas escalonadas. Comprueba la estructura, muros y taludes, el saneamiento y el estado de la piscina.
La Pineda — Casas y bloques de apartamentos entre pinos, cerca de la playa. Inspecciona la corrosión de barandillas y armaduras, las humedades en plantas bajas y el estado de las cubiertas.
