An illustrative example of the structure, depth, and format of a Denludi pool diagnostic report. All building details are fictional.
The following illustrates the structure and level of detail in a Denludi report. Real reports include laboratory data, photographs, and building-specific findings.
The pool at Torre Rivadavia presents a combination of water chemistry imbalance, early-stage structural deterioration in the grout lines of the shallow end, and an undersized filtration system that is unable to maintain adequate water clarity under normal occupancy conditions.
The most pressing concern is the pH consistently below the recommended range, which is accelerating corrosion of the grout and metal fittings. This should be addressed before any structural repairs are undertaken, as regrouting into chemically aggressive water will not hold.
Consistently acidic. At this level, chlorine effectiveness is reduced and the water is actively corroding plaster and metal surfaces. Immediate correction required before any structural work.
Low alkalinity is contributing to pH instability. Sodium bicarbonate addition required as part of the chemistry correction protocol.
Within acceptable range at time of testing. However, effectiveness is compromised by the low pH — the actual sanitising capacity is lower than the reading suggests.
Significantly low. Combined with acidic pH, the water is aggressively undersaturated — actively dissolving calcium from pool surfaces. Calcium chloride addition required.
No concerning indicators detected in laboratory analysis. Water is microbiologically safe at time of sampling.
Grout lines between tiles are failing across approximately 4 square metres of the shallow end west wall. The failure pattern is consistent with chemical attack rather than movement — confirming the water chemistry issue as the primary cause. Regrouting should follow chemistry correction, not precede it.
Three tiles on the entry steps show hollow sound when tapped, indicating loss of adhesion. No displacement yet, but intervention recommended within the current season to prevent water ingress behind the tile layer.
No structural cracks were observed in the pool shell. Expansion joints are intact. The deterioration is currently limited to the finish layer and is not indicating structural movement.
For a pool of this volume and the building's occupancy profile, a turnover time of 4–6 hours is appropriate. The current system achieves approximately 8.5 hours. This explains persistent cloudiness during peak periods and is contributing to the overall chemical load on the water.
The sand filter media shows signs of channelling and has not been replaced within manufacturer-recommended intervals. Efficiency is reduced. Replacement recommended before the next season.
The pump motor and impeller are operating normally. No replacement required at this time.
The following table organises recommended interventions by urgency. Cost ranges are indicative and based on current market rates for the Buenos Aires metropolitan area. Actual quotes from contractors should be obtained using this document as a technical reference.
| Priority | Intervention | Rationale | Indicative Range |
|---|---|---|---|
| Immediate | Water chemistry correction protocol | All structural repairs are ineffective until pH and alkalinity are stabilised | Materials cost only |
| Immediate | Dosing system calibration | Prevents recurrence of chemistry imbalance after correction | Service call |
| This season | Grout replacement — shallow end west wall | After chemistry stabilisation; prevents water ingress and tile loss | Contractor quote required |
| This season | Step tile re-adhesion (3 tiles) | Before displacement occurs and water reaches substrate | Contractor quote required |
| This season | Filter media replacement | Restores filtration efficiency; should coincide with seasonal maintenance | Contractor quote required |
| Plan ahead | Filtration system upgrade | Undersized for building's occupancy; long-term solution to persistent cloudiness | Engineering assessment first |
The above illustrates the structure and approach. A real assessment is based on your building's actual pool, equipment, and water chemistry.
