⚙️ Inputs – Room With Slop – 4 Sides

Side A – Top (m) – Nominal Nominal

m

Top wall – 5.00 m – opposite C – one more/less concept – border line through wall

Side B – Right (m) – One More +0.15 m MORE

m

Right wall 4.15 m – MORE than Left D – one wall more than other – one more one less

Side C – Bottom (m) – One Less -0.15 m LESS

m

Bottom wall 4.85 m – LESS than Top A – 0.15 m less – different sizes – irregular quadrilateral

Side D – Left (m) – Reference

m

Left wall 4.00 m – LESS than Right B – opposite walls different – 4 sides only NOT pentagon

🏔️ Slop of Room – Slope – Through Room

Slop Type – Direction of Slope Slope Through RoomLow at Bottom C → High at Top A – Slope ALow at Top A → High at Bottom C – Slope CLow at Left D → High at Right B – Slope BLow at Right B → High at Left D – Slope DLow at Center → High at Edges – ValleyHigh at Center → Low at Edges – Crown

Mortar Thickness – Low Side (mm) – Minimum Min – High Side Floor

Thickness at low side of slop – where floor high – e.g., 20 mm min

Mortar Thickness – High Side (mm) – Maximum – Slop Correction Max – Low Side Floor – Slop

Thickness at high side of slop – where floor low – e.g., 50 mm max – difference = slop – 30 mm slop in this example

Slop / Slope Value (mm) – Auto Calculated – Through Room

Slop = High - Low = 50-20 = 30 mm slop through room – mortar through room with slop

Mortar Mix Ratio (Cement : Sand)1:4 – Standard – Strong1:5 – Medium1:6 – Lean

Wastage (%) – Includes Slop

Slop of Room Concept – Mortar Through Room With Slop:
- Room floor not level – slop/slope through room – one side high, one side low
- Low side needs thin mortar (20 mm) – high side needs thick mortar (50 mm) – slop 30 mm
- Volume = Area × Average Thickness = Area × (Low+High)/2 – accounts for slop
- Example: Area 20.02 m² × (20+50)/2=35 mm avg = 0.70 m³ – vs 0.40 m³ without slop – 75% more mortar due to slop
- One more one less: A 5.00 vs C 4.85 = 0.15 m diff – B 4.15 vs D 4.00 = 0.15 m diff – irregular quadrilateral
- Border line through each wall + 90° ref + slop arrow shows slope direction – 4 sides only NOT pentagon – Clean dashboard – Old search erased

🗺️ Plan View + Section – Room With Slop – One More One Less

Top-down mortar layer + side section showing slop – different sizes i.e. one more one less – border line through each wall – slope arrow

Room boundary – irregular 4 sides Mortar layer – sloped – avg 35 mm Slope direction – slop arrow

Plan: Scale 1 grid = 1 m • Section: Shows low 20 mm → high 50 mm slop through room – One more one less A vs C, B vs D – Border line + 90° ref

Slop Analysis – Border Line + Slope:
A 5.00 m Top vs C 4.85 m Bottom = 0.15 m diff – one more one less – Top more than Bottom
B 4.15 m Right vs D 4.00 m Left = 0.15 m diff – one more one less – Right more than Left
Slop: Low side 20 mm (high floor) → High side 50 mm (low floor) = 30 mm slop through room – mortar through room with slop – need slope correction
Border line through each wall + 90° blue ref + slope arrow – Shows room boundary irregular 4 sides – 130°/70° large or 89.5°/90.3° small diff – One more one less – 4 sides only NOT pentagon

Note: Results are estimates with slop. Mix 1:4 standard mortar. Volume = Area × Avg Thickness (Low+High)/2. Slop increases volume significantly – Low 20 mm vs High 50 mm = Avg 35 mm = 75% more than flat 20 mm. Always add wastage for spillage and slop. Different sizes i.e. one more one less – irregular quadrilateral – slop through room – border line making right angle – Old search erased – Clean dashboard.
