ASEIS also offers a
Construction durability glossary
and a
Building pathology glossary
First and foremost, this is a construction dictionary with English explanations. Given the difficulty that faces the Romance language speaker to relate to technical English (and the other way around), whenever possible, the corresponding equivalents are given (where genus choices are possible, only the masculine is shown). Some reference standards are also indicated. If you have a better translation, please e-mail it to us for consideration / inclusion / credit.

Defect (F défaut, R defect) The non-conformity of the result of a test with the specification for a characteristic (ISO 2071).

Delamination (F délaminage, R destratificare) The breakdown of a material by separation of the layers of which it is composed. C The separation of the slab usually at the level of reinforcement in a plane roughly parallel to the upper surface, and is caused by corrosion of the steel. Whether visible on the surface or not, delaminations should be repaired as they indicate a high level of corrosion activity and may lead to significant structural weakening.
Depreciation Decline in value of a house due to wear and tear, adverse changes in the neighborhood, or any other reason.

Down payment
1. The portion of the sales price to be paid by the purchaser to the seller upon the signing of the agreement of sale.

earnest moneyA deposit made to bind the conditions of a sale of real estate or of a contract for certain services. If the sale goes through, the earnest money is applied against the down payment. If the sale does not go through, the earnest money may be refundable.

Fatigue (R oboseala) The weakening of a material caused by repeated or alternating loads; may be used in conjunction with either static or dynamic loading (BS 2787)
Fault (F 1.imperfection, vice, R 1.defect, 2.falie) 1) Any defect which impairs normal operation (BS CP1013); 2) geologic discontinuity where seismic events start. See failure & defect
Faultmeter A Georgia Digital instrument that measures vertical displacement between joints with a digital readout. Measurements are positive or negative and be recorded for a number of joints
FHWA (US) Federal Highway Administration
Fissure (F fissure, R fisura, crapatura) crack or split
